3M™ SJ352 Hook and Loop Fastener Tape

3M™ SJ352 Hook and Loop Tape: features, uses and comparison

The 3M™ SJ352 Hook and Loop Tape is an industrial benchmark for temporary or permanent fastenings that require no drilling or screwing.

Its hook-and-loop double-sided design offers reliable adhesion on a wide range of surfaces, even in demanding environments.

Designed by 3M, it combines robustness, ease of installation, and reusability, making it ideal for industry, electronics, or interior design.

Introduction to the 3M™ SJ352 Hook and Loop Tape

The 3M™ SJ352 Hook and Loop Tape is a removable and reusable fastening system. It consists of two complementary strips, one hook side and one loop side, that fasten together with simple pressure.

This tape is designed for industrial and professional applications. It provides a strong mechanical bond while allowing for repeated opening and closing without significant performance loss.

Composition and structure of the SJ352 tape

The SJ352 is based on a woven polypropylene backing, which is robust and moisture-resistant. The adhesive side features a high-performance acrylic adhesive that ensures durable fixation on a wide variety of surfaces.

The hooks and loops are molded from nylon, a material recognized for its resistance to abrasion and repeated opening cycles. This structure ensures a longer lifespan than entry-level hook and loop tapes.

Key structural features include:

• Backing: woven polypropylene
• Hooks and loops: nylon
• Adhesive: high-performance acrylic
• Resistant to moisture and common solvents
• Compatible with smooth, painted, metallic, and plastic surfaces

At Dagobert Industrie, we offer this tape for various uses: attaching signs, cable management, equipment organization, or temporary workshop assembly.

Technical properties and performance of the 3M™ SJ352

The 3M™ SJ352 is a hook-and-loop fastener tape designed for repeatable fastenings without glue or screws. It consists of two complementary sides: a hook side and a loop side that assemble with simple pressure.

The substrate is made of woven nylon, known for its abrasion resistance and durability over time. The acrylic adhesive on the back of the tape ensures a solid bond on smooth surfaces: metal, plastic, varnished wood, and glass.

This tape withstands service temperatures up to 107 °C, making it suitable for moderately hot industrial environments. Its resistance to moisture and UV rays also qualifies it for outdoor applications.

Key characteristics of the SJ352:

• Material: woven nylon
• Adhesive: pressure-sensitive acrylic
• Max. service temperature: 107 °C
• Peel strength: high
• Color: black
• Reusable: yes, several hundred cycles

Compared to standard hook and loop tapes, the SJ352 stands out for its temperature resistance and the robustness of its acrylic adhesive, which is suited for industrial requirements.

Applications and sectors for the SJ352 tape

The 3M™ SJ352 hook and loop tape is designed for repeatable and removable fastenings that require no tools. It adapts to a wide variety of rigid or semi-rigid surfaces.

Its high-performance acrylic adhesive allows it to hold onto plastic, painted metal, lacquered wood, or composites. It is a reliable choice wherever screws or permanent glue should be avoided.

Sectors where the SJ352 is most commonly used:

• Industry and production: mounting signage, protective covers, identification labels on machines
• Electronics and cabling: securing cable bundles, organizing components in electrical cabinets
• Layout and retail: fixing POS (Point of Sale) materials, displays, lightweight partitions in stores
• Medical and laboratory: attaching small, frequently removable equipment without damaging surfaces
• Transport and vehicles: holding interior trim, storage in utility vehicles or buses

The SJ352 is distinguished by its resistance to repeated opening and closing cycles. It retains its mechanical properties even after several hundred uses.

Product	Manufacturer	Type	Peel Strength	Main Use
SJ352	3M	Hook & Loop with adhesive	High	Industrial removable fastening
SJ3526	3M	Low-temp Hook & Loop	Medium	Cold environments, refrigerated warehouses
Dual Lock™ SJ3550	3M	Mushroom-to-Mushroom	Very high	High-load fastening, vibrations
Velcro® Industrial	Velcro Companies	Hook & Loop with adhesive	High	General use, layout

At Dagobert Industrie, we offer the SJ352 to professionals who need a clean, reversible, and long-term durable fastening solution.

Comparison: 3M™ SJ352 versus other hook and loop tapes on the market

The industrial hook and loop tape market offers several references. Here is how the 3M™ SJ352 compares to the competition.

Comparative table of main industrial hook and loop tapes

Product	Manufacturer	Material	Shear Resistance	Temperature Resistance	Adhesive	Main Use
SJ352	3M	Nylon	High	Up to 107 °C	High-performance acrylic	Heavy-duty industrial fastening
SJ3551 / SJ3552	3M	Nylon	Very high	Up to 107 °C	High-performance acrylic	Very heavy-duty industrial fastening
SJ3526	3M	Nylon	Moderate	Up to 66 °C	Standard acrylic	Light to moderate fastening
Velcro® One-Wrap	Velcro Industries	Nylon / Polyester	Moderate	Up to 60 °C	No adhesive (self-gripping)	Cabling, storage
Dual Lock™ SJ3560	3M	Polypropylene	Very high	Up to 107 °C	High-performance acrylic	Rigid fastening, vibrations

The SJ352 stands out for its high-performance acrylic adhesive, adapted to difficult surfaces (paint, metal, plastic).

Compared to the Dual Lock™ SJ3560, it offers a softer grip and easier removal. The Dual Lock is better suited for applications subject to high mechanical vibrations.

Compared to the Velcro® One-Wrap, the SJ352 provides superior thermal resistance and permanent attachment thanks to its adhesive backing. The One-Wrap remains ideal for temporary uses without a target surface.

At Dagobert Industrie, we recommend the SJ352 for any industrial fastening requiring reliability, durability, and resistance to demanding ambient conditions.

Installation tips and best practices

Surface preparation is the most critical step. Clean the substrate thoroughly with isopropanol or a suitable degreaser before application.

Avoid wet, dusty, or greasy surfaces. Poorly prepared surfaces drastically reduce the adhesion strength of the SJ352 tape.

Press firmly along the entire length of the tape after application. Using a pressure roller ensures optimal contact between the adhesive and the substrate.

Allow a 24-hour setting time before subjecting the assembly to a load. The acrylic adhesive reaches full strength after this period.

For curved or irregular surfaces, cut the tape into short segments. This facilitates application and improves contact across the entire surface.

For maintenance, clean the hooks regularly with a soft brush. Accumulated fibers and debris degrade gripping performance over time.

• Recommended application temperature: between +10°C and +38°C
• Do not apply to PTFE, polyethylene, or polypropylene without a suitable primer
• Avoid prolonged exposure to UV light without additional protection
• Cutting with a utility knife: always on a flat surface, using a fresh blade
• Store the tape away from heat and moisture before use

FAQ - 3M™ SJ352 Hook and Loop Tape

1. What is the difference between 3M™ SJ352 and SJ351?

SJ352 is the loop side of the system, while SJ351 is the hook side. Both combine to form a complete assembly. You must always use both references together to achieve fastening.

2. Does SJ352 hold on irregular surfaces?

The adhesive backing of the SJ352 is designed to adhere to flat and smooth surfaces. On a rough or porous surface, adhesive strength will be reduced. In this case, thorough cleaning with isopropanol before application significantly improves results.

3. Is SJ352 moisture resistant?

Yes. The 3M™ SJ352 tape is formulated to resist moderate exposure to moisture. It is suitable for slightly humid indoor environments. For prolonged exposure to water or intensive outdoor use, it is best to verify the technical limits in the product datasheet.

4. Can it be cut to the desired size?

Yes, the SJ352 is easily cut with scissors or a utility knife. This is a practical advantage on construction sites or in workshops: you can adapt the exact length to the need, with no waste.

5. How many hooking/unhooking cycles does it withstand?

The 3M™ SJ352/SJ351 hook and loop system is designed to withstand several hundred opening and closing cycles. The actual lifespan depends on usage conditions: applied load, manipulation frequency, and the presence of dust or debris that clogs the fibers.

6. What are the typical applications for SJ352 at Dagobert Industrie?

At Dagobert Industrie, this product is mainly used for attaching lightweight signs, cable management, organizing components in racks, and the removable assembly of plastic or metal parts. It is a clean solution with no screws or permanent glue.
